Nowadays when Energy costs are skyrocketing and the awareness to environmental issues is increasing, we all want to reduce energy consumption and have a greener lifestyle. Heating & cooling are much more than issues of comfort; greenhouse gases produced, among others, by industrial processes, may excessively raise the temperature of our planet to hazardous levels. Meitav-tec is committed to the environment and fights global warming by developing state of the art thermostats with smart, energy saving algorithms, and offers the following tips, to implement at home or office in order to save energy, save money and save our planet!

Energy Saving Tips
Adjust set point temperature up a few degrees - Instead of cooling your home to 22°C, try 24°
or 25°C. For every degree you lower your thermostat,
you can approximately save 3% on your electricity costs.
Generally, lowering your thermostat by five degrees
will make a significant impact on your energy bill.
Just as a reference, the United Nations plans to save
US$ 100,000 on electricity costs in August only by limiting
the cooling temperature in the UN building to 25°C.

A Programmable Thermostat is one of the easiest ways to save energy; it automatically adjusts temperature according to your pre-programmed settings.Meitav-tec’s thermostats offer weekly settings (7 days or 5-1-1), with four programs per day to regulate temperature both in summer and winter, when you are asleep or away.

3During the summer, if weather is mild, use the Fan On option in Meitav-tec’s
thermostat. Air temperature is not reduced, but people feel cooler due to the breeze.
If you use air conditioning, a ceiling fan will allow you to raise the thermostat setting
about 2°C with no reduction in comfort. If weather is cold and Heat
is required, use the Auto-Fan option; the Fan will continue
working until room reaches required temperature.

Building Management System can be a highly
economic solution for central HVAC systems.
Maxinet 7.0, Meitav-tec’s web based, mini-BMS
application can ultimately save users 20%-30% of
overall electricity expenses. Building supervisors
can adjust thermostats of unoccupied areas within
a building during weekends, holidays or non-working
hours. Maxinet enables the operator to “treat” each
zone individually, turn it on/off, switch to another
mode, or alternatively change set point
temperature.

B.M.S.
In a Multi-Zone system,
Cool / Heat only the spaces you
are in.
Zone your cooling system to
cool / heat only occupied areas.
This will greatly reduce energy
consumption.

6Meitav-tec’s thermostats can include a Window Contact
input, an additional energy saving feature, particularly useful
in hotels or office buildings. If user opens a window/ door in
an air-conditioned room, the system will automatically switch
to Economy mode or will shut down. A lot of energy may be
wasted if, for example, in hot weather, user opens the window
while thermostat is in Cool mode; indoor temperature is
immediately affected from the outdoors hot air, causing the
system to work hard to cool and thus consume more energy.

Occupancy Sensor automatically turns
off air-conditioning in unoccupied spaces, such
as offices, classrooms or conference room.
Meitav-tec’s thermostats offer Infra Red Occupancy
Sensor inputs to detect volumetric change in a room.
This is most effective in spaces, which are often
unoccupied; energy costs can be reduced
dramatically. 12V power supply to the
Occupancy Sensor is also included, so
no additional power supplier is required.

Another effective way to save energy is to have set point temperature displayed on thermostat rather than room temperature. The user psychologically assumes that ambient
temperature is high/low, depending on the season, and therefore doesn’t change temperature
often. Likewise, Meitav-tec’s thermostats feature adjustable set point limits, to be pre-defined
by maintenance people, in order to regulate temperature demand and save energy costs. User
may enter 10°C as a set point temperature, exceeding set point limit; however, system will cool to
minimum of 18°C, for example, according to the pre-programmed limit.

Use the Lock Buttons option in Meitav-tec’s
thermostats to maintain desired temperature
settings. By locking the buttons, user is unable to
change mode, fan speed or set-point temperature,
but can only switch the system On or Off.
Eliminating the possibility
to switch between Heat and Cool or change set point temperature too
frequently reduces energy consumption of the HVAC system, resulting in
lower energy costs.

Clean or replace filters once a month,
especially during peak cooling or heating season.
Dirty filters cost more to use, overwork the
equipment and result in lower indoor air quality.
